Could have happened. The Apollo Program killed a lot of more sustainable projects, because it sucked up pall funding, and then died of being way to expensive, killing all innovation for decades. Ironically, without the race to the Moon, space technology would likely be far more advanced today. Project Orion would have been by far the best. It didn't require any fancy tech, materials, or manufacturing, but could deliver insane payloads, and not just to LEO, but anywhere in the Solar System. It only needed advanced nukes, thousands per launch, but that apparently wasn't an issue.
The problem was they were actually TOO massive to work. Bono was one of the few to address the likely damage such large boosters would do during launch. He had his ROMBUS launch not from a normal launch pad but one situated in the middle of a bowl shaped concrete ring which would be partially filled with water at launch. In addition to a massive sound-suppression water spray system the standing water in the 'bowl' would take on a concave shape at launch due to the engines firing and that and the shape of the bowl would direct the sound upwards so sparing the Cape and surrounding area from massive over-pressure sound waves. As the ROMBUS rose the shape would change and gradually 'defocus' the sound allowing the vehicle to pass through without harm. (In theory anyway :) ) The Boeing "Big Onion" used and artificial lake for takeoff and landing for the same reason with several of these 'launch bowls' spread out along the shore and the LV floated and towed into position for launch or recovery. Vehicles like the NEXUS and AMPLV were suggested to be launched from offshore platforms but the distance needed for such huge vehicles was prohibitive. (It doesn't help that sound carries better over/through water either)
The concept of those "Generation Ships" was (and i guess is) a crazy possibility that could have been done with those simple yet giant Orion rockets! I wish we had more SciFi exploring the social aspects of all that besides the mess that "Ascension" was.
I think its Crazy how the Saturn V is over 50 years old and still the most powerful rocket to ever successfully launch to space and that we might finally beat it with not one but two rockets in the coming few years (SLS and Starship)
Actually, the USSR's Energia rocket was more powerful than Saturn V, and the Urugan derived from both Energia and the Buran Shuttle would have been fully reusable.

@1:40, nice shout out to the reusable Saturn S1 concept from Convair! What's funny is that it was literally about a paragraph in the entire "NEXUS" study even though it had been worked on (after NASA asked it be included :) ) just about as much as the actual "NEXUS" itself. Not sure if the proposed recoverable version of the SII stage was given the same treatment, (only illustrations are essentially a slightly smaller S1 re-drawn) but it's interesting that the actual 'question' NASA asked Convair was about a NEXUS-like vehicle that could mount heavier upper stages (such as a larger NERVA or large self-deploying space station) AND still fit in the VAB. Hence the 'squashed' S1 and SII which would lower the overall height (and still fit on the MLP :) ) enough for those upper stages to clear the top of the VAB doors. Think you might address the Goodyear METEOR (2,500ft long and 1500ft in diameter "Space Station" made by disassembling the third stage of a fully reusable, fully manned three stage to orbit vehicle, ya gotta love the esthetic :) ) and METEOR LV and it's successor METEOR Jr?
Dude! I always enjoy your videos. Always informative and entertaining. I don't know why, but this current video is out of this world great. Keep it up!
Who captured the image on your desktop at ~1:55 with the aurora and tree lining up perfectly? That looks wonderful and I'd love to see a full resolution image.
I also remember reading of a design back in the late '80s/early '90s where they went for musk-style horizontal scaling. The rocket would be lots of long tanks next to each other, alternating fuel/lox with an engine at the joint of each tank, with stages being nested inside each other.
The current size is based upon affordability at this time. As the business case drives larger rockets, they will be built. Once infinite government budgets are not available, then business constraints come in to play.
That's not really true...historically, roads and railroads, as well as large ships were developed without a market right at hand. They were betting on expansion creating a market that would sustain their model and give them a tidy profit. I'd say that since the railroad, and then the highway, and then the cargo ship basically built the entire 20th century...It works.
I don't know why, but it seems most people either worship Elon, or dispute him and everything he does. The fact that people were saying, making a larger rocket is stupid, is ridiculous. I'm not going to grovel at elons feet and pretend he's the real life tony stark, but I'm not going to snob at the things his company gets right. It boggles my mind how people don't realize the reason space x is successful, is because elon hires good engineer. You can think he's personally an idiot, but there's no denying his companies have made some very impressive things, whether he personally designed them or not.
I believe he addressed that in a q&a with "most of my time in making a video is spent searching for images to use" so the answer is "the internet with lots of patience"
Assembling it in orbit over a period of years and then firing it up in space would make more sense, imo. Seeing those blasts from hundreds or thousands of miles up would be just as impressive.
Larry Niven's Footfall ought to get a mention - great fiction - spoiler alert: the Orion launch just destroys the manufacturing plant and the surrounding town.
@@AwfulnewsFM Earth-based Orion launch attempts made sense in the 1960s, when both USA and USSR tested nukes to their hearts' content. Back then, I don't think anyone would've batted an eyelid at a few dozen nuclear explosions in quick succession, considering the Soviets had detonated the Tsar Bomba early in the decade. Now we have the START treaties in effect, and the environmental implications are considerable (nuclear fallout, etc.).
I think the shuttle is a derivative of the double space planes concept. They made the first stage non reusable first then added the side boosters because the engines weren’t that powerful
STS was a compromise between NASA and DoD to be able to steal a Soviet spy satellite and take it back to Edwards/Groom Lake. NASA wanted a crew ferry to send people to work on things launched on Saturn Vs, DoD wanted massive crossrange landing capability to grab a spysat and bring it back on one orbit, and then Nixon cancelled the Saturn program. And once it was built, the Air Force conveniently forgot about it and never used that capability. And fourteen people died because it was kind of a crap design.
@@randycampbell6307 Well regardless. Using the same craft to leave earth especially a manned craft then require it to land back on earth is incredibly stressful for the craft and incredibly dangerous for the crew. Space craft should stay in space. Then you send the human crew, fuel, and a separate lander which can be different depending on where it’s to land say Earth, Mars, the Moon. Sure way more expensive but allows for much more versatility and modifications.
Image all the fish floating to the top of the ocean from the continuous explosion from that giant rocket engine, the fishing boats would be in a race from the safety exclusion zone as soon as been cleared to collect up all those fish's.
Am glad Project Orion got a quick shout-out at the end, but if you are talking about big spacecraft, that is the Big Daddy of them all. The "mid-range" Orion was 4,000 tons (so still bigger than the Saturn V), but the "Super Orion" clocked in at 8 MILLION tons (3 million of which was cargo) and was 400m wide and 450m tall.
I mean - no matter how you put it it would be modern technology. I'm sure all of them woild basically be possible but doubt some of them would've been feasible with 60s-70s technology.
covering daedalus engines and that project would be a great follow up to this video! especially with them maybe being in KSP2 down the line in the road map!
I love this channel. Does anyone know where Scott reads all this stuff? I never got taught this stuff in uni because it just doesn't directly get involved in the exercise of design, but it is stuff that can guide the designer!
I’ve never heard anyone mention the aquatic sonic issues something like Seadragon would have created. They were among of the (many) issues that led to then end of underwater nuclear testing, and the energy involved in one of those launches would be nearing that scale.
@@HuntingTarg You're not the first to wonder, but I can't remember the answer. I think it might be in one of Scott's older videos where he built a Star Raker in KSP, but I might be thinking of something else.
A prerequisite is someone find big / heavy enough payload to fully utilize such rockets. A cargo container ship is also more efficient if it is bigger. But we don't build them until we got enough goods to ship frequent enough and loading / unloading those cargo fast enough.
@@KuK137 No, not really. Combustion instability is great example of his point. Rockets are under _extreme_ forces. As you scale things up, those forces also scale,and things can get funky.
There was a film project based in Sydney, Australia called Man Conquers Space. This used the Chesley Bonestell vehicles. Sadly the film was never completed. There are trailers on you tube. They are brilliant, a vision of what might have been. As for launch vehicle designs, there is Space Shuttle by Dennis R Jenkins. I bought a copy on eBay from a guy in California called Rick Berman. It is a good read.
Scott, thank you so much for using the term "plug nozzle" engine rather than the much-abused "aerospike" when what you;re talking about actually is a plug-nozzle engine! Any chance of an update on detonation engines? I only heard of Oblique Wave Detonation Engines the other day - interesting idea. I'm curious as to what kind of ISP RDE's and OWDE's might get though.
Japan's SS-520-5 weighs a little under 3 tons at launch, is about 31 feet in height, 20 inches diameter and successfully placed a 4kg cubesat into low Earth orbit on its maiden launch 3 Feb 2018
I would love some MORE detail on ALL of these! This is so interesting. Why didn't they work? Where there any viable prototypes? Please, please expand on this video! :)
13:45 Yeah, I understand that ratio.. but fuel tanks should not be pressurized? When we scale a pressurized tank, for the same pressure the dry mass of the tank increase exactly at the same rate than the volume, so I dont see benefits on that regard, I hear that we can save on avionics, but that is NOTHING in comparison to the over all dry mass. I always wanted to know how scale benefit the rocket performance and why.. But never read nothing detailed on that topic.
Now I am wondering how big a Starship V2 could be? If the concept of scaling up rockets works for SpaceX, would they try to make Starship even bigger? Curious what you think @ScottManley 🤔
Surely if it works and they find the need, they'll go for the original starship design that's almost twice as big (mass) featured in the start of this video?
They could go with triple-booster Starship Heavy, if they need about x3 payload. There is no demand for such beasts in the foreseeable future, though (about 1000 ton max payload to LEO in expendable config!!!). Smaller and simpler way to launch occasional heavy and/or oversized payloads is to have an expendable version of the upper stage, with traditional fairing.
This may be repetition of something I posted elsewhere about Sea Dragon. In the summer of 1962, after my 2nd year of college, I was privileged to work for Robert C. Truax at Aerojet-General's Advanced Propulsion Laboratory in Sacramento, California. Among the things I was involved in was doing calculations for 20, 40, 60, 80 and 100 million pound thrust first stage Sea Dragon designs! How did I happen to get the job? Well, back in 4th grade, 1954, I had this crazy idea about using "controlled" atomic explosions to power rocket ships. My uncle, who had been in the Navy in WWII, suggested I send the idea to the Bureau of Aeronautics, which I did. I got a very nice letter from a, then, Cdr. R.C. Truax, encouraging me. (I still have the letter!) In 1962, when the Air Force announced Project Orion, with a similar concept (with some actual testing with high explosives), I wrote to Truax to see if my kid's dream had sparked an idea. His reply was that he didn't think so, but how would I like to work for him at Aerojet, which I did. Another idea he played with was using some propellants that would self-pressurize because they boiled at room temperature. So long as they were under pressure, they remained liquid. He would walk around with a clear bottle of Freon, so you could see it in its liquid form, until he squeezed a valve release, whereupon the vapor would spray out of the nozzle. He used the similar concept with supersaturated steam in Evil Kineavals' motor cycle that was attempted to fly across the Snake River canyon. When the cycle failed to get enough thrust to fly across the canyon, and Kineval was forced to use a parachute, Truax "accepted blame" for not getting the water hot enough. Personally, I don't think it was intended to make it across, because Kineval would have been split like a fish if he landed!
I was literally just reading up on Saturn MLV, Nova and Phillip Bono rocket design variants before I knew you were gonna release this today. Seems any SHLV design exceeding 100 tons in payload mass has to get wider and not taller than 100m.
Most of that is to do with how the VAB at the Cape is constructed. Of course, there is the TeamVision Jupiter III concept which just says "Hey we're gonna need a bigger building, that's fine, right?"
Thrust to weight plays a role here. If you roughly approximate that rocket parts and fuel have a certain average density, then an engine with a given footprint and thrust to weight ratio can only support a limited height of "rocket stuff" above it. I guess with current thrust to weights this comes out to 100m
There is only one reason to build "skinny" and that is tool or transportation limits. There are some aerodynamic reasons, but at scale those start to matter much less. Girth beats length...even in engineering.
The best giant space thing is the plan to have the Saturn S-1C do a boostback burn and be grabbed out of the air under parachutes by a ridiculously huge helicopter powered by ramjets on the rotor tips, to be built by Hughes.
Fun fact: One of the Heavy-lift Vehicles from NASA's SPS study (the Alternate Design at 10:31) has similar payload to Starship (120t), yet only 4000t mass when full. Which is less than simply the fuel mass of Starship (a 20% boost), and even with some mass reserve! Apparently, aluminium construction/winged flyback is a pretty efficient design!
The concerns of instability for the Sea Dragon main engine are overblown and rooted in it's very low operating pressure. Combustion instability scales linearly with volume but not pressure which is why most rocket engines operate at several orders of magnitude higher pressure. However as you scale up the motor there's no need to lengthen the combustion chamber as the optimal length is the same no matter how wide or large it's volume is being driven by the characteristic burn length of the fuel mix. This means it's actually extremely easy to prevent any instabilities from reaching the chamber walls before the mass flow of the exhaust has already swept it out of the nozzle completely. Obviously this only works for rocket motors that are fifty feet wide or so. That's how the motors, the single most expensive rocket component per pound were to be made in a ship yard and out of welded diamond plate.
What is an empire but all humanity under the direction of a single mind? I was right, but I dreamed too small. I have seen how much more we have to be. Winston Daurte approves these designs.
"If you don't have the numbers, it's just an opinion" Hope that's an original Scott, 'cuz I'm gonna use it often!!!! Another great episode, Thankx......
The thing I cannot reconcile about Sea Dragon is, how would they ever make a pressure-fed first and second stage feasible? The thicker the rocket gets, the walls of the tanks have to be proportionally thicker to withstand the same pressure, so wouldn't the tanks be just too heavy to reach orbit?
Nope. The tanks could be proportionally lighter because the internal volume is expanding faster than the perimeter. Thus less tank is needed per pound of propellant.
The tanks would have to be somewhat thicker at the bottom, simply because of the higher head-pressure. But the needed hoop-strength is constant for diameter. A pressure of 20 bar for a 5 meter wide tank would remain 20 bar for a 50 meter tank; and, say ~4mm steel remains 4mm. The steel required is 10 times greater (for a given height), but the volume enclosed is 100 times. Could such a booster perform on balloon-stiffnes alone? If so, having a one-use design starts to make sense, as long as you're not doing crew-rated launches, but rather just throwing materiel into LEO.
@@dillonvandergriff4124 I don't think this is how pressure vessels work. As the radius increases, the curvature decreases, and to have the tension strength high enough for the pressure, the walls need to be thicker. Even before anyone starts using propellant.
pressure vessel mass ratios remain constant regardless of the size, you can check out the derivation why on the Wiki page for pressure vessels. What this means is that the mass ratio of a huge rocket at a certain pressure can be exactly the same as for a small vehicle at the same pressure. It's just that the pressure in this case is pretty low for a rocket
Hold on... Starship v3 is the same height as sea dragon. And an expended starship v3 may be able to lift the dame amount as sea dragon despite being 3× thinner
Fun fact: One of the Heavy-lift Vehicles from NASA's SPS study (the Alternate Design at 10:31) has similar payload to Starship (120t), yet only 4000t mass when full.

I'm sort-of weirdly surprised and unsurprised at the same time. It looks like a big coincidence but it's probably not. If ol' Musky's parents named him after that and told him so, it would have a big influence on him.

Another good video Scott. Chronologically speaking, instead of saying it looks like something Elon Musk would design, it would be more accurate to say that the earlier designs are what Musk is drawing inspiration from.
I have a copy of the English version of the "Exploration of Mars" book, it was a Christmas present from my granddad in about 1963, very inspiring. I think I put it in the charity bag. Aaaargh! And now I see there's a copy going for nearly £250 on Amazon!
People skeptical of the starship are mostly skeptical about the economics of it and the over promises from Elon... Not if it will actually fly.. it probably will.
@@HalNordmann not surprised, and the door they are implementing seams to point in that direction as well..with reduced available volume Vs the original concept.

Moar boosters!!! Thanks for this awesome video, Scott Manley. It's a lot of fun thinking about the great beasts that could have been.
That is the best quickie you have ever done. Congrats SM
@1:40, nice shout out to the reusable Saturn S1 concept from Convair! What's funny is that it was literally about a paragraph in the entire "NEXUS" study even though it had been worked on (after NASA asked it be included :) ) just about as much as the actual "NEXUS" itself. Not sure if the proposed recoverable version of the SII stage was given the same treatment, (only illustrations are essentially a slightly smaller S1 re-drawn) but it's interesting that the actual 'question' NASA asked Convair was about a NEXUS-like vehicle that could mount heavier upper stages (such as a larger NERVA or large self-deploying space station) AND still fit in the VAB. Hence the 'squashed' S1 and SII which would lower the overall height (and still fit on the MLP :) ) enough for those upper stages to clear the top of the VAB doors.
Think you might address the Goodyear METEOR (2,500ft long and 1500ft in diameter "Space Station" made by disassembling the third stage of a fully reusable, fully manned three stage to orbit vehicle, ya gotta love the esthetic :) ) and METEOR LV and it's successor METEOR Jr?
I know it gets said a lot, but the UR-900 is *the* most kerbal thing ever designed.
12:19 "...it looked like a Proton that just kept on adding stages and tanks after it should have stopped."
Point supported.
It’s good to think big back then especially sea dragon big

@@Double_Vision Thanks!
I also remember reading of a design back in the late '80s/early '90s where they went for musk-style horizontal scaling. The rocket would be lots of long tanks next to each other, alternating fuel/lox with an engine at the joint of each tank, with stages being nested inside each other.
The current size is based upon affordability at this time. As the business case drives larger rockets, they will be built. Once infinite government budgets are not available, then business constraints come in to play.
That's not really true...historically, roads and railroads, as well as large ships were developed without a market right at hand. They were betting on expansion creating a market that would sustain their model and give them a tidy profit.
I'd say that since the railroad, and then the highway, and then the cargo ship basically built the entire 20th century...It works.
Scott Manley tweaking Musketeers. Love it!
I don't know why, but it seems most people either worship Elon, or dispute him and everything he does. The fact that people were saying, making a larger rocket is stupid, is ridiculous. I'm not going to grovel at elons feet and pretend he's the real life tony stark, but I'm not going to snob at the things his company gets right. It boggles my mind how people don't realize the reason space x is successful, is because elon hires good engineer. You can think he's personally an idiot, but there's no denying his companies have made some very impressive things, whether he personally designed them or not.
I'm really starting to love Scott's tongue-in-cheek tone whenever he mentions 420.
Scott where do you get all of these awesome concept art from? I love looking at them
I believe he addressed that in a q&a with "most of my time in making a video is spent searching for images to use" so the answer is "the internet with lots of patience"
Ahh the shoutout to the GAME OVER!! meme is beautiful
An Orion launch would be spectacular (from a distance!)
Even more spectacular close up - just not safe.
Assembling it in orbit over a period of years and then firing it up in space would make more sense, imo. Seeing those blasts from hundreds or thousands of miles up would be just as impressive.
@@paulrockatansky77 it's sad because on of the good points of Orion was the amazing lift off to orbit capability.
Larry Niven's Footfall ought to get a mention - great fiction - spoiler alert: the Orion launch just destroys the manufacturing plant and the surrounding town.
@@AwfulnewsFM Earth-based Orion launch attempts made sense in the 1960s, when both USA and USSR tested nukes to their hearts' content. Back then, I don't think anyone would've batted an eyelid at a few dozen nuclear explosions in quick succession, considering the Soviets had detonated the Tsar Bomba early in the decade. Now we have the START treaties in effect, and the environmental implications are considerable (nuclear fallout, etc.).
Wait... Scot, it has flown, and de-orbited. Although it hasn't hit the sticks yet, it did make orbit.
Thanks for the episode.
I think the shuttle is a derivative of the double space planes concept. They made the first stage non reusable first then added the side boosters because the engines weren’t that powerful
We also don’t use it anymore for various reasons and the shuttle wasn’t designed for long distance space missions.
Other way around, the Boeing "Space Freighter" was designed from the work done on the Shuttle Orbiter.
STS was a compromise between NASA and DoD to be able to steal a Soviet spy satellite and take it back to Edwards/Groom Lake. NASA wanted a crew ferry to send people to work on things launched on Saturn Vs, DoD wanted massive crossrange landing capability to grab a spysat and bring it back on one orbit, and then Nixon cancelled the Saturn program. And once it was built, the Air Force conveniently forgot about it and never used that capability. And fourteen people died because it was kind of a crap design.
@@randycampbell6307 Well regardless. Using the same craft to leave earth especially a manned craft then require it to land back on earth is incredibly stressful for the craft and incredibly dangerous for the crew. Space craft should stay in space. Then you send the human crew, fuel, and a separate lander which can be different depending on where it’s to land say Earth, Mars, the Moon. Sure way more expensive but allows for much more versatility and modifications.
@@DeliveryMcGee Crap design? Only 2 failures out of how many flights?
I like videos like this because they give me plausible yet wonderful technology to put into stories.
The sea dragon would have been the greatest rocket of all time
I would AGREE in saying the greatest _non-nuclear_ rocket.
A vehicle based on _PROJECT ORION_ would have been the greatest _nuclear_ rocket.
You could actually play little league baseball minus the outfield in the first stage engine bell.

Hopefully not. All time is a lot of time.
Am glad Project Orion got a quick shout-out at the end, but if you are talking about big spacecraft, that is the Big Daddy of them all. The "mid-range" Orion was 4,000 tons (so still bigger than the Saturn V), but the "Super Orion" clocked in at 8 MILLION tons (3 million of which was cargo) and was 400m wide and 450m tall.
I'd love to see a day when people build these rockets just to see if they would have worked. imagine seeing that!
I mean - no matter how you put it it would be modern technology. I'm sure all of them woild basically be possible but doubt some of them would've been feasible with 60s-70s technology.

I love this channel. Does anyone know where Scott reads all this stuff? I never got taught this stuff in uni because it just doesn't directly get involved in the exercise of design, but it is stuff that can guide the designer!
Another superb snapshot of history! Keep it up.
I’ve never heard anyone mention the aquatic sonic issues something like Seadragon would have created. They were among of the (many) issues that led to then end of underwater nuclear testing, and the energy involved in one of those launches would be nearing that scale.
I don't think Sea Dragon would've been very bad for aquatic life. Nowhere near as much energy involved. It would also have been done in deep water.
Scott, I don’t know how you keep just making such interesting and engaging videos… even just reading from teleprompter right? You are great at that

Already watched this video like three or four times, can't get over the ridiculousness of these.
When it comes to spaceplanes, the Star Raker is an absolute beast!
I can't but wonder if it had some connection to the James Bond story "Moonraker."
@@HuntingTarg You're not the first to wonder, but I can't remember the answer. I think it might be in one of Scott's older videos where he built a Star Raker in KSP, but I might be thinking of something else.
Ya'll not going to mention the "Saucer" concept at 13:24 ??
I had a feeling that increasing scale might make rockets more efficient. This is obviously really great news.
I don't know if this is true for rockets, but i do know that it is true for Ekranoplans.
800 meters size Ekranoplan when
But scaling a rocket is not the same as scaling a bridge. Mass reveals problems never encountered before.
A prerequisite is someone find big / heavy enough payload to fully utilize such rockets. A cargo container ship is also more efficient if it is bigger. But we don't build them until we got enough goods to ship frequent enough and loading / unloading those cargo fast enough.
@@KuK137 No, not really. Combustion instability is great example of his point. Rockets are under _extreme_ forces. As you scale things up, those forces also scale,and things can get funky.
So Manley and so good. Love the vids!
Amazing artistic drawings of a proposed rocket design by Concodroid at 1:46 . I wonder what their career is 'cause they should become an artist.
good idea
There was a film project based in Sydney, Australia called Man Conquers Space. This used the Chesley Bonestell vehicles. Sadly the film was never completed. There are trailers on you tube. They are brilliant, a vision of what might have been.
As for launch vehicle designs, there is Space Shuttle by Dennis R Jenkins. I bought a copy on eBay from a guy in California called Rick Berman. It is a good read.
Scott, thank you so much for using the term "plug nozzle" engine rather than the much-abused "aerospike" when what you;re talking about actually is a plug-nozzle engine! Any chance of an update on detonation engines? I only heard of Oblique Wave Detonation Engines the other day - interesting idea. I'm curious as to what kind of ISP RDE's and OWDE's might get though.
Excellent presentation! Loved seeing the collaboration with Amy Shira Teitel. I miss her since she has not posted in a while. Thanks
Hazegrayart 's channel has great animations for most of the concepts described here!
I love these TH-cam video titles, these are big on paper compared to an actual Starship block 1. lol.
Great video as always, Scott! Makes me wonder about the opposite, though: what were the smallest orbital launchers ever proposed?
- To my knowledge the early 60's 4 stage Scout X-1 sounding rocket put a dinky little satellite into LEO several times.
Japan's SS-520-5 weighs a little under 3 tons at launch, is about 31 feet in height, 20 inches diameter and successfully placed a 4kg cubesat into low Earth orbit on its maiden launch 3 Feb 2018
I would love some MORE detail on ALL of these! This is so interesting. Why didn't they work? Where there any viable prototypes? Please, please expand on this video! :)
They simply weren’t funded because Congress didn’t want to support such a massive project. Von Braun’s rocket was rendered unnecessary by technology.
@@scottmanley Thank you!
13:45 Yeah, I understand that ratio.. but fuel tanks should not be pressurized? When we scale a pressurized tank, for the same pressure the dry mass of the tank increase exactly at the same rate than the volume, so I dont see benefits on that regard, I hear that we can save on avionics, but that is NOTHING in comparison to the over all dry mass.
I always wanted to know how scale benefit the rocket performance and why.. But never read nothing detailed on that topic.
cool. This video was actally needed! Good Job!
Now I am wondering how big a Starship V2 could be? If the concept of scaling up rockets works for SpaceX, would they try to make Starship even bigger? Curious what you think @ScottManley 🤔
Surely if it works and they find the need, they'll go for the original starship design that's almost twice as big (mass) featured in the start of this video?
@@Tiwack01 that would be really interesting, why did they chose the scaled down version, do you know?
They could go with triple-booster Starship Heavy, if they need about x3 payload. There is no demand for such beasts in the foreseeable future, though (about 1000 ton max payload to LEO in expendable config!!!). Smaller and simpler way to launch occasional heavy and/or oversized payloads is to have an expendable version of the upper stage, with traditional fairing.
@@denysvlasenko9175 that would be sick
I love finding out about weird concepts like these!
0:30 “4-1/2 thousand tons”? I have driven freight trains that have weighed less than that. You kind-of forget how big this thing is.
This may be repetition of something I posted elsewhere about Sea Dragon. In the summer of 1962, after my 2nd year of college, I was privileged to work for Robert C. Truax at Aerojet-General's Advanced Propulsion Laboratory in Sacramento, California. Among the things I was involved in was doing calculations for 20, 40, 60, 80 and 100 million pound thrust first stage Sea Dragon designs! How did I happen to get the job? Well, back in 4th grade, 1954, I had this crazy idea about using "controlled" atomic explosions to power rocket ships. My uncle, who had been in the Navy in WWII, suggested I send the idea to the Bureau of Aeronautics, which I did. I got a very nice letter from a, then, Cdr. R.C. Truax, encouraging me. (I still have the letter!) In 1962, when the Air Force announced Project Orion, with a similar concept (with some actual testing with high explosives), I wrote to Truax to see if my kid's dream had sparked an idea. His reply was that he didn't think so, but how would I like to work for him at Aerojet, which I did.
Another idea he played with was using some propellants that would self-pressurize because they boiled at room temperature. So long as they were under pressure, they remained liquid. He would walk around with a clear bottle of Freon, so you could see it in its liquid form, until he squeezed a valve release, whereupon the vapor would spray out of the nozzle. He used the similar concept with supersaturated steam in Evil Kineavals' motor cycle that was attempted to fly across the Snake River canyon. When the cycle failed to get enough thrust to fly across the canyon, and Kineval was forced to use a parachute, Truax "accepted blame" for not getting the water hot enough. Personally, I don't think it was intended to make it across, because Kineval would have been split like a fish if he landed!
It’s fun to learn about how Kerbal Space Program just imitated real life (designs)…
Great job Scott
Nope
I was literally just reading up on Saturn MLV, Nova and Phillip Bono rocket design variants before I knew you were gonna release this today. Seems any SHLV design exceeding 100 tons in payload mass has to get wider and not taller than 100m.
Most of that is to do with how the VAB at the Cape is constructed.
Of course, there is the TeamVision Jupiter III concept which just says "Hey we're gonna need a bigger building, that's fine, right?"
I do have a soft spot for the MLV designs, they could’ve been perfect for the Apollo Applications Program
Is there actually an interesting read to read up on this stuff or do you mean browsing the web?
Thrust to weight plays a role here. If you roughly approximate that rocket parts and fuel have a certain average density, then an engine with a given footprint and thrust to weight ratio can only support a limited height of "rocket stuff" above it. I guess with current thrust to weights this comes out to 100m
There is only one reason to build "skinny" and that is tool or transportation limits. There are some aerodynamic reasons, but at scale those start to matter much less.
Girth beats length...even in engineering.
1:22 I love the added touch of Blue Origen's rocker. hahah
Personally my favorite concept was Boeing's LMLV. I think it was proposed in 1968, and could carry about 2000 tons to orbit (I think?)

There's something really cool and nostalgic about these space-age illustrations.
The best giant space thing is the plan to have the Saturn S-1C do a boostback burn and be grabbed out of the air under parachutes by a ridiculously huge helicopter powered by ramjets on the rotor tips, to be built by Hughes.
That truly was hilarious. The helicopters literally looked like Saturn V first stages with propellers installed.
The tip of the blades would have been supersonic even at the minimum speed
Ooh! I'd forgotten about the ramjet helicopter thing. I read about it years ago. :D
I hope it is so. Beer can is what it reminds me of. Worried about Max q with such a tall structure.
Fun fact: One of the Heavy-lift Vehicles from NASA's SPS study (the Alternate Design at 10:31) has similar payload to Starship (120t), yet only 4000t mass when full. Which is less than simply the fuel mass of Starship (a 20% boost), and even with some mass reserve! Apparently, aluminium construction/winged flyback is a pretty efficient design!
The concerns of instability for the Sea Dragon main engine are overblown and rooted in it's very low operating pressure. Combustion instability scales linearly with volume but not pressure which is why most rocket engines operate at several orders of magnitude higher pressure. However as you scale up the motor there's no need to lengthen the combustion chamber as the optimal length is the same no matter how wide or large it's volume is being driven by the characteristic burn length of the fuel mix. This means it's actually extremely easy to prevent any instabilities from reaching the chamber walls before the mass flow of the exhaust has already swept it out of the nozzle completely. Obviously this only works for rocket motors that are fifty feet wide or so. That's how the motors, the single most expensive rocket component per pound were to be made in a ship yard and out of welded diamond plate.
this is great! Thanks Scott!

I'd love to hear more about the pressure wave problems associated with large rocket engines.
Cheers from Alaska,
Greg Chaney
That was great, more please
The thing I cannot reconcile about Sea Dragon is, how would they ever make a pressure-fed first and second stage feasible? The thicker the rocket gets, the walls of the tanks have to be proportionally thicker to withstand the same pressure, so wouldn't the tanks be just too heavy to reach orbit?
Nope. The tanks could be proportionally lighter because the internal volume is expanding faster than the perimeter. Thus less tank is needed per pound of propellant.
Could they be thin walled, with internal stays ? I don't know , just an idea
The tanks would have to be somewhat thicker at the bottom, simply because of the higher head-pressure. But the needed hoop-strength is constant for diameter. A pressure of 20 bar for a 5 meter wide tank would remain 20 bar for a 50 meter tank; and, say ~4mm steel remains 4mm. The steel required is 10 times greater (for a given height), but the volume enclosed is 100 times.
Could such a booster perform on balloon-stiffnes alone? If so, having a one-use design starts to make sense, as long as you're not doing crew-rated launches, but rather just throwing materiel into LEO.
@@dillonvandergriff4124 I don't think this is how pressure vessels work. As the radius increases, the curvature decreases, and to have the tension strength high enough for the pressure, the walls need to be thicker. Even before anyone starts using propellant.
pressure vessel mass ratios remain constant regardless of the size, you can check out the derivation why on the Wiki page for pressure vessels.
What this means is that the mass ratio of a huge rocket at a certain pressure can be exactly the same as for a small vehicle at the same pressure. It's just that the pressure in this case is pretty low for a rocket
'UR-900 is a Proton with unreasonably MOAR BOOSTERS'
Truly Kerbal.
Hold on... Starship v3 is the same height as sea dragon. And an expended starship v3 may be able to lift the dame amount as sea dragon despite being 3× thinner
12:04 "With 15 cores" - The picture you show only has 12 cores, right? Where are the other 3?
That space freighter concept sounds really cool! Maybe scaled down to maybe 30-40t to LEO, it might be economical

Isnt this book "Projekt Mars" the one were von Braun also descibed the Martian gov structure and the title he chose for the Mars leader was Elon?
I'm sort-of weirdly surprised and unsurprised at the same time. It looks like a big coincidence but it's probably not. If ol' Musky's parents named him after that and told him so, it would have a big influence on him.
I still believe NASA should revisit the Boeing Space Freighter and commission a modern version of it.

Chronologically speaking, instead of saying it looks like something Elon Musk would design, it would be more accurate to say that the earlier designs are what Musk is drawing inspiration from.

People skeptical of the starship are mostly skeptical about the economics of it and the over promises from Elon... Not if it will actually fly.. it probably will.
Although I have some doubts about its payload. I have done some math on it, and maximum reusable payload is only somewhere in the 60-80t range.
